US is only decades away from widespread water shortages, scientists warn

Much of the United States could be gripped by significant water
shortages in just five decades’ time, according to predictions
made in a new study. … In the researchers’ projections, water
supply is likely to be under threat in watersheds in the
central and southern Great Plains, the Southwest and central
Rocky Mountain States, California, and areas in the South
(especially Florida) and the Midwest.
